Granted that was meant as a rhetorical question, but I think regulation is often written by young consultants because everyone tends to back the buck on to someone else. However, when it comes to the process that actually choses which regulation to go with that's often a range of special interests each fighting to protect their individual pieces. Conceder cap and trade which is clearly less efficient than simply taxing carbon. While it might seem like a terrible idea for anyone with a few lobbyists and the assumption that they can specify an exception for their industry it can become a huge boon at the cost of those with less influence.
